Application filed February 23; 1918. Serial NOE-2183812.

To all whom tt may-wmem Be it known that I, PHILIP STEVENS,-fi

citizen of the United States, and a resident of Adams township, Lucascounty, in the State of Ohio, have invented a certain new and usefulMixer; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the characters ofreference marked thereon, which form a part of this specification.

My invention relates to mixers. It particularly relates to mixers formixing dry materials such as feed for stock, also for mixing grains forpoultry, and the like.

The invention may be contained in different forms of construction andused for different purposes. I have selected a form of constructioncontaining the invention as an example of such constructions and shalldescribe it hereinafter. The construction selected is illustrated in theaccompanying drawings.

Figure 1 of the drawings is a side view of a feed mixer, Fig. 2 is anend view, Fig. 3 is a sectional view of the mixing drum, Fig. 4: is asectional view showing the manner of securing the cover. Fig. 5 is anend view of the cover, Fig. 6 is a sectional view taken on the line 66indicated in Fig. 3.

1, Fig. 1, is a frame on which is supported a drum 2. The drum 2 isprovided with end plates or castings 3 forming the heads of the drum.The plates or heads 3 are provided with flanges 4 and 5. Between theheads 3 and the flanges 4L and 5 is located a deep corrugated or sinuousband forming the side of the drum. The sinuous side forms a plurality ofpockets 7 each of which is made narrower at the mouth 8 than at a pointsubstantially the center of the pocket. Moreover, the pockets are madeconsiderably wider than the distances between the adjoining sides of theadjoining pockets. These dimensions however may be changed withoutdeparting from the spirit of the invention, the pockets being ofsuflicient depth and size to gather and hold the material and carryportions of it up over the top of the material when the drum is rotated.

The sinuous band '23 is held in place between the flanges 4: and 5 andbetween the head 3 'bymeans of the tiebolts 9 located preferably 011 theoutside of the band or side of the drum but in close proximity of theinner flange 4. When the parts are thus secured together by the tiebolts 9, the side and the pockets are held in position and bulging isprevented. By this arrangement, the parts may be readily assembled andsecured together.

The drum is provided with a cover 10, one end of which fits under theflange 5, the other end being provided with a flange 11 that overlapsone of the heads 3, a portion of the head 3 being cut away as at 12 toreceive one end of the cover 10. The flange 11 is provided with a notchor slot 13 in which is located a winged screw 14 that is threaded intoone of the heads 3. In securing the cover in position, one end isinserted under the flange 5 of one head and the cover is then placedover the ends 15 of the side of the drum and the flange 11 is pusheddown between the winged nut 14: and the other head 3, whereupon thewinged nut 14 may be screwed down so as to bind on the flange 11 andhold the cover 10 in its position. If desired, bolts 16 may be locatedwithin the ends 15 and beneath the edges of the cover. The bolts 16 areplaced close to the flange 5 and the ends 15 may be turned or bentaround the bolts 16 so as to securely hold the ends of the side 7 andprevent their being bent in filling the drum from bags or baskets orreceptacles from which the grain is poured into the drum.

The drum is suitably supported on the standard 1 by means of a shaft 17that passes through the drum. The shaft 17 is connected to a crank 18whereby the drum may be rotated by a turning of the crank 18. The shankof the crank 18 may be provided with notches l9 and a pawl 20 may beattached to the side of the standard 1 for looking the drum in twopositions, one in its filling position, namely, when the cover islocated in the upper side of the drum and in the position of emptyingthe drum, namely, when the opening that is normally closed by the coveris located on the underside of the drum. A hopper 22 formed of sheetmetal may be located around the drum to receive the material from thedrum, particularly when it is being emptied whereby the material may bedirected into a bin or chute.

I claim: In a mixer, a drum having end plates, a

pair of flanges located on each end plate, the side Wall being bentaround the said a sinuous side Wall located between the tWo last namedbolts, a cover supported on 1 flanges and the end plates, edges of theend the ends of the side Walls and the two last plates extending backand forth between the named bolts and means for securing the flanges,the side Wall forming curved pock cover in closed position.

ets, bolts for securing the end plates and the In testimony whereof, Ihave hereunto side Wall of the drum together, two of said signed my nameto this specification.

bolts located in spaced relation, the ends of PHILIP STEVENS.
